Sidelobe Suppression of Antenna Array Using Harmony Search Algorithm

In this paper, sidelobe suppression problem in the antenna radiation pattern is taken into consideration. Dealing with this optimization problem, an algorithm that is called Harmony Search Algorithm (HSA) is proposed and compared with existing and used algorithms in the literature, Particle Search Algorithm (PSO) and Artificial Bee Colony (ABC). A statistical comparison is carried out to examine the differences in performance. The results show that HSA can be used to suppress sidelobes with considerably short processing time.
